Spin-based quantum computers have the potential to tackle difficult mathematical problems that cannot be solved using ordinary computers, but many problems remain in making these machines scalable. Now, an international group ...

Researchers from the Moscow Institute of Physics and Technology, ETH Zurich, and Argonne National Laboratory, U.S, have described an extended quantum Maxwell's demon, a device locally violating the second law of thermodynamics ...

Researchers with the Department of Energy's Oak Ridge National Laboratory have demonstrated a new level of control over photons encoded with quantum information. Their research was published in Optica.

Professor Michelle Simmons' team at UNSW Sydney has demonstrated a compact sensor for accessing information stored in the electrons of individual atoms—a breakthrough that brings us one step closer to scalable quantum computing ...

Sebastian Krinner is the first winner of the Lopez-Loreta Prize at ETH Zurich. The physicist has a clear goal: he wants to build a quantum computer that is not only powerful, but also works without errors.

The experimental mastery of complex quantum systems is required for future technologies like quantum computers and quantum encryption. Scientists from the University of Vienna and the Austrian Academy of Sciences have broken ...

Quantum computers that are capable of solving complex problems, like drug design or machine learning, will require millions of quantum bits—or qubits—connected in an integrated way and designed to correct errors that ...

Researchers from the Moscow Institute of Physics and Technology (MIPT), Aalto University in Finland, and ETH Zurich have demonstrated a prototype device that uses quantum effects and machine learning to measure magnetic fields ...
